If you cannot reuse parts of other SVG signs or drawings, you can
convert bitmaps on this site <http://www.vectorizer.io>.

I wanted to make a SVG logo. I had a crappy 4.7 kB jpg. I found a better
388 kB eps and I converted it to 2.7 kB png. Then I ran png though that
site and I got a PERFECT 6.5 kB SVG, not bad for an XML file !!!

SVG is scaling nicely because it doesn't use bitmaps but Bézier curves
<http://en.wikipedia.org/wiki/B%C3%A9zier_curve> that are scaling perfectly.

One of the best advice to make SVG drawings is to use a suitable grid
and snapping to it.

Best regards,

André.
